Assessment of the internal connection of an angled screw channel system.

Statement Of Problem: The angled screw channel (ASC) design has been well accepted for implant prostheses. However, investigation into the behavior of the ASC connection is sparse.

Purpose: The purpose of this in vitro study was to assess the effect of cyclic loading on the internal connection of an ASC system compared with straight access systems by measuring reverse torque values (RTVs) and using microcomputed tomography (µCT) imaging.

Evidence that transverse variability of critical current density can greatly mitigate screening current stress in high field REBCO magnets.

Plastic damage of REBCO (REBaCuO, where RE=rare earth) coated conductors by screening current stress (SCS) is a significant concern for ultra-high-field superconducting magnets. Indeed, the third Little Big Coil (LBC3), a REBCO magnet that generated a record, high field of 45.5 T, showed wavy plastic damage produced by excess SCS in all pancakes except two made with single-slit conductors having their slit edges pointing inward towards the magnet center.

Prognostic Implications of the Bethesda System in Fine-Needle Aspiration for Follicular Thyroid Carcinoma.

Context.—: Fine-needle aspiration is an effective tool for sampling thyroid nodules; its results are classified according to the Bethesda System for Reporting Thyroid Cytopathology (BSRTC), whose categories define malignancy risks.

Objective.

Presenteeism among nurses: An integrative review.

Background: Presenteeism, a phenomenon in which employees attend work despite physical or mental limitations, is prevalent among nurses and has negative implications for patients, healthcare organizations, and nurses themselves.

Objective: We aimed to present the current state of knowledge on presenteeism in nursing, focusing on prevalence rates, reasons, influencing factors, and consequences.

Design: We performed an integrative review.

Migration routes and adult survival of the critically endangered yellow-breasted bunting Emberiza aureola.

Migratory animals rely on multiple sites during their annual cycles. Deteriorating conditions at any site can have population-level consequences, with long-distance migrants seen as especially susceptible to such changes. Reduced adult survival caused by persecution at non-breeding sites has been suggested a major reason for the catastrophic decline of a formerly abundant, long-distance migratory songbird, the Yellow-breasted Bunting Emberiza aureola.
